摘要
目的探讨QT离散度(QTd)对系统性红斑狼疮(SLE)患者早期心脏受累的检测价值。方法选取46例诊断为无临床心脏受累证据的SLE患者为研究组,63例体检健康者为对照组,对比分析两组受检者的QTd。结果无临床心脏受累证据的SLE患者的QTd为(55.6±24.6)ms,对照者为(20.1±5.6)ms,二者比较差异有统计学意义(t=5.97,P<0.01)。结论检测无临床心脏受累证据的SLE患者的QTd,能够早期发现SLE患者潜在的心肌损伤。
Objective To evaluate the QT dispersion （QTd） in SLE patients without overt cardiac involvement.Methods 46 SLE patients without cardiac involvement were selected as experimental group,and 63 healthy people were selected as control group.QTd of the two groups were analyzed.Results QTd of SLE patients without cardiac involvement is（55.6±24.6）ms,while QTd of control group is （20.1±5.6）ms,and the difference of the two groups is significant（t=5.97,P0.001）.Conclusion Detecting QTd in SLE patients without cardiac involvement can find potential myocardial damage in early stage.
